FASCIA SYSTEM ron A FLAT ROOF BACKGROUND OF THE INVENTION The instantinvention is in the field of building structures, and relatesspecifically to the structure of the marginal edge portion of a fiatroof deck wherein there is provided a waterdam or cant extending alongthe periphery of the roof deck, the roof itself comprising a pluralityof layers of roofing material overlaid with a layer of gravel bitumen. Agenerally vertically disposed strip of material such as aluminum or thelike, commonly known in the trade as a fascia, extends longitudinallyalong the waterdam or cant, covering the visible surface thereof andthus forming a pleasing appearance. The structure also includes a linermember extending along the upper edge of the fascia and overlying thelayers of roofing material which project over the inclined waterdam orcant, and anchor means having a hook portion for easy and effectivelocking engagement against a marginal edge of the fascia to retain thefascia and the liner in predetermined position with respect to the roofdeck. The construction describes a simple and easily installable systemfor the marginal edge of a roof deck, providing a pleasing appearanceand at the same time insuring against seepage of water or gravel bitumenmaterial down the face of the building.

In prior art constructions known to applicant, a fascia strip isprovided, together with means for securing and holding the fascia stripin place and preventing water leakage down the face of the building,wherein the securing members extend the entire length of the fasciastrip, with screws spaced apart along the length of the securing memberto fasten the assembly to the roof deck. In addition to the fact thatthese constructions in some instances do not provide adequate sealingagainst water leakage, they are generally quite difficult to install onthe roof, principally because of the fact that the securing or anchoringmember is of such length as to be cumbersome and difficult to handle andmaintain properly positioned while being screwed to the roof deck.Applicant's structure on the other hand utilizes anchor means which arerelatively small, an ideal size being about 2 inches wide, which areprovided with a hook portion easily engageable with a projecting head onthe fascia and which because of their size are more conveniently handledfor installation of the system on the roof. In addition, the provisionof the interfitting fascia and liner members provides a waterproof roofedge construction which obviates the possibility of unsightly waterstains down the face of the building.

Other objects, advantages and meritorious features will more fullyappear from the following specification, claims and accompanyingdrawings, wherein:

FIG. I is a perspective view of the marginal edge of a roof deck showingmy improved fascia system installed thereon;

FIG. 2 is a cross-sectional view taken along line 2-2 of FIG. 1; and

FIG. 3 is a partial cross-sectional view similar to FIG. 2 showing apreferred form of my fascia system.

Referring now more particularly to the drawings, there is shown themarginal edge portion of a roof deck for a building, the top of thebuilding sidewall being shown at in FIG. 1 sunnounted by a cap 12, thebase roof deck of the building 14 being in alignment with the wall cap12. Overlying the base roof deck 14 are a plurality of layers of roofingmaterial generally indicated by the numeral 16 surmounted by a layer ofgravel bitumen material 18. Extending along the marginal edge of theroof and secured to the cap member 12 as by means of nails or the like20 is a waterdam or cant 22 having a generally vertical portion 24extending above the roof deck and an inclined portion 26 having ahorizontal edge portion secured to the roof by fastener 20. The waterdamor cant 22 extends completely around the periphery of the roof, and themembers shown may be made out of galvanized metal or the like as shown,or may be made out of wood. The gravel bitumen layer 18 terminatessubstantially at the lower edge of the inclined cant 26 while the layersof roofing material continue on up the inclined surface, with thetopmost layer extending over the peak of the cant and downwardlyoverlying the vertical surface a short distance.

An elongated fascia strip 28 is provided which is disposed generallyvertically overlying the upright portion of the cam 22, and having aslightly outwardly flared lower end 30 shaped to define an upturnedchannel which embraces the lower extremity 32 of the cant, which isslightly outwardly flared to cooperate with the channel on the fasciastrip. The inclined lower end of the fascia strip provides a grip edgeand the relationship between it and the lower edge of the cant providesa simple connection therebetween. Referring specifically to FIG. 2, thefascia strip 28 is provided adjacent its upper end with a pair ofspaced-apart inwardly directed projecting portions 34 and 36respectively, the lower portion 36 characterizable as a projecting lipwhich engages the folded over edge of the upper layer of roofingmaterial shown at 16a, while the upper portion 34 terminates in amarginal bead 38 extending therealong. The fascia strip 28 is preferablymade out of sheet metal, such as extruded aluminum or the like which isprovided in relatively long lengths arranged in end-to-end relationalong the roof edge, there being provided joint members (not shown) ofsimilar cross-sectional shape which overlie the marginal edges ofadjacent fascia strips and conceal the slight space left therebetween.In some instances, the joints might be eliminated, and the fascia strips28 made to overlap each other.

The projecting portions 34 and 36 of the fascia strip 28 define agenerally U-shaped channel within which there is positioned the upperend of ali'nerflashing strip 40, which conforms to the shape of thefascia strip channel and is additionally provided with a lower endportion overlying the upper layer of roofing material 16a. The linerflashing strips 40 are disposed in end-to-end relation, and are ofappreciable length, preferably each being equal to approximatelyone-half the length of the flashing strip 28, for reasons to bedescribed hereinafter. Spaced apart along the roof edge assembly are aplurality of anchor means or clips 42, which are preferably made out ofaluminum or the like, each of the clips 42 being relatively narrow, say2 inches or so, with respect to the length of the fascia strip and linerstrip. The upper end of each clip 42 is generally hook shape, as shownat 44, terminating in a locking edge 46 which engages and locks againstthe upstanding shoulder of the bead 38 which runs the length of thefascia strip 28. Adjacent the hooklike portion 44, the clip 42 exhibitsa projecting intermediate portion 48 which projects into the channelformed by fascia portions 34 and 36 and bears against the liner member40. Extending downwardly and away from the upper end of the clip, thereis a lower end portion 50 which overlies the correspondingly shapedportion of the liner portion and maintains the liner in intimate contactwith the roofing material 16a. The marginal edge of the clip 42 isdisplaced from the plane of the clip in a generally triangularconfiguration as shown at 52 to provide a more rigid edge which bearsagainst the roofing material 160 and holds it securely in place. Thelower marginal edge of the liner member 40 is correspondingly shaped toprovide rigidity to that member, and insure bearing engagement againstthe roofing material throughout the length of the liner stripintermediately clip members 42. A securing means in the form of a screw54 is utilized to secure the clip 42 to the cant 26, and hold the entirefascia assembly in proper position. The screw 54 is preferably made outof stainless steel or other suitable metal because of its properties ofhigh strength and resistance to corrosion.

As can be seen from an examination of FIG. 2, with the lower end 30 ofthe fascia strip 28 hooked over the lower edge of the cant 22, thefascia strip upper end is positioned so that the projecting lip 36engages against the folded over layer of roofing material, and with thefascia strip so positioned, the liner member 40 is inserted within thechannel and extended over the inclined surface of the roofing material.One of the anchor means or clips 42 is thereafter installed to completethe assembly by engaging its hook 46 over the bead 38 on the fasciastrip and then swinging the clip 42 in a clockwise direction until itassumes the position shown in FIG. 2. The stainless steel screw 54 maythen be screwed through the roofing material 16 into the cant 26 tosecure the entire assembly in place.

As can be seen from FIG. 2, with the parts assembled, the clip member 42exerts a downward and inward force against the uppermost projection 34of a fascia strip 28, in turn urging the projecting lip 36 into intimatecontact against the uppermost layer 16a of roofing material. The fasciastrip is thus positively held in position at its upper end, withoutexerting any appreciable force against the lower end 30 of the fasciastrip and the interfitting edge 32 of cant 22. Therefore there is nopossibility that the fascia strip 28 will be distorted nor that thelower end of the cant 22 will be pulled away from the cap member 12.

Referring now specifically to FIG. 3, there is shown a preferredembodiment of the elements forming the roof edge construction for use ona roof identical to that illustrated in FIG. 2 and previously described.The roof edge construction and the cant 22 are identical to that shownin FIG. 2, and a preferred fascia strip 60 is provided having a lowerend portion (not shown) of identical shape as to the portion 30 of thefascia strip 28 previously described. Spaced from the upper end of thefascia strip 60 is an inwardly projecting lip portion 62 running thelength of the strip of similar configuration to and for the same purposeas the projecting lip 36 on fascia 28. At its upper end, the strip 60 isshaped into a generally channellike portion 64 terminating in a marginalbead 66 as shown. A liner strip member 68 is provided similar inconstruction to the member 40, but shaped adjacent its upper endconforming to the shape of the fascia strip section 64 to interfitwithin the fascia member and extend downwardly away therefrom andoverlie the roofing material 16a in similar fashion. A clip or anchormember 70 is provided, having a first end portion 72 of hooklikeconfiguration embracing the bead 66 and in locking engagement againstthe bead shoulder as shown, an intermediate portion 74 extending betweenand interfitting in the recess formed by the fascia portion 64 and 62and retaining the liner 68 thereagainst, and an opposite end portion 76of substantially identical shape to the end portion 50 of clip 42.Securing means in the form of a screw or the like 54 is utilized to fixthe clip 70 to the cant 22, and retain the entire assembly in properposition with respect to the roof deck.

As stated above, the fascia sections 28 or 60 and the liner members 40or 68 are of appreciable length, while the clips for anchor members 42or 70 are comparatively small. The dimensional relationships between thevarious parts of the assembly and purpose for such relationships will bedescribed with reference to the structure shown in FIG. 3, it beingunderstood that the same relationships apply to the structure shown inFIG. 2. The waterdam or cant 22 may be made of any convenient length,and as the roofing material extends upwardly over the inclined surfaceof the cant, the abutting edges of adjacent cant sections are covered bythe roofing material, obviating any water leakage problems. The cant 22as shown is well known in the industry, and does not form a part of theinstant invention. Taking first of all the fascia strip 60, we willassume that such is manufactured of metal such as aluminum in lengths offeet, for purposes of illustration. According to the example, the linerflashing sections 68 would be manufactured with extruded aluminum or thelike of about 5 feet in length. There would thus be provided twosections of liner for every section of fascia. As previously stated theanchor means or clips shown at 70 in FIG. 3 would be approximately 2inches in length measured longitudinally of the fascia strip and linermember. When installing the liner member 68 into the fascia strip, aslight cap would be left between adjacent liners, and a clip 70 ishooked over the fascia strip bead and positioned to bridge the gap andoverlie the space between adjacent liner members. The screw 64 isthereafter engaged through the clip, the layers of roofing material andthe cant. However such screw does not pierce either of the adjacentliner members 68. In addition, substantially centrally along the lengthof each liner member 68 there is provided an additional slip memberwhich is installed in similar fashion, the securing screw 54 for suchclip extending through the liner member. Thus, while there is providedfor each liner member 68 in effect three clips 70, one at each end ofthe liner member and one midway along its length, only one securingscrew actually extends through the liner member 68. This results in theliner member being held in its proper relationship with respect to thefascia strip and roof deck at three points along its length, but beingpierced by a screw at only one point, which provides for expansion andcontraction of the liner strip due to changes in temperature without anytendency to coupling of the liner strips and without exerting anyexpansion forces against the securing screws 54 which might tend toloosen them. Adjacent abutting ends of the fascia strip 60 are alsospaced apart slightly a predetermined distance to allow for expansionand contraction of the strips due to climatic changes withoutinterference therebetween, the joints being covered by a cover plate orjoint member (not shown) overlying the fascia strip.
